invention relates to hydrocarbon burners in which the fuel is exteriorly atomizedfby means of any expansive `fluid such asy air or steam.

. Y Thel principal object of the invention is the above type having a construction permitting the flare o-r spreadof the atomized fuel to beV vvaried without changing-the volume or pressure of the expansive fluid. v

-A' further object of the invention is the Y .production of a'burner Vwhich may be constructedentirely` from bars and plates of standard size thereby lessening the cost of manufacture.

vproduction of a hydrocarbon burner having a construction permitting the fuel tube'or pas- I sageway to be vertically and bodily adjusted to vary the space between its'dis'charge'end tions thereof hereinafter'more particularly described and then specified in the claims.

`In the accompanying drawing illustrating f a practical embodiment of the invention:

Fig. 1 is a section taken through the burner. Fig. 2 is a frontv elevation thereof. Fig. 3 is a bottom plan view of the forward end of the expansive vfluid tube in spaced rel lation to the fuel tube.

Fig. 4 is a perspective view of the forward end of the fuel tube. Y f

Fig. 5 is a section on the line 5-5 of Fig 1. Fig. 6 is' a perspective view'of the bearing for the lip forming the end vof the expansive fluid tube. n.

A further lobject of the inventioniis the4V wall of theitlllr A5 isinclined ceiving ltherebetween' a cap or. head 10 lwhich f i issecuredto said tube by the screw 11. The head 10 is provided kwith an inclined slot 12 terminating in a horizontal slot 13, saidk slots formingwith the inclined wall 8 and lianges' 9 a fuel-receiving` chamber communicating with the fuel passagewayy 6. Extending Ythroughthe base of the cap or'head 1() and communicating with the horizontal slot 13': are a plurality of spacedperforations 14;: providing outlets for theffuelafterit has f* flowed from the passageway 6y and into the chamber formed vby the slots-12 and 13.

The fuel tube 5 is provided witha recess 15 therein, the upper wall of whichv is slot-` sof ted and receives the shank offa screw 16 Y which is screwed through thev wall 8.@ The head of the screw l-lies within the recess 15. This-arrangement not only permits the eor tube 5 to be moved horizontally lbutfto beraised bodily vertically to and away'from thewall 3 by manipulation of the screw 16l .in an obvious manner. As shown inF ig. 1v

said `tube 5 is in its lowermostvertical position and is shown restingon a supporting block 17 having an inclinedfac'e 18, said `supev porting block being detachably-secured to.`

. 'both,sideplates 1 by suitable screws v19..

20 indicates'a squared atomizingfluidmtube:v

throughA which the atomizing fluid, such as air or steam, passes to atomize the fuel flowing from the perforations 14. The forward end'of said tube is rounded as at 21 and is slidably received by a head comprising a bearing22' having'an:inclinedrface 23 provided with "projecting, horn-s 24. 'The' forward end 21 of the tube is cut` in a plane in.-Vr clined to. thehorizontal axis. of the tube wherebywhen said' endis in fully-advanced..

position it'supper surfaceiwill' be flush with the surface of the inclined face 23.V By cutting the end of said tube in the manner described a lip 24 havingafroundedg end ist provided on the outer end thereof which is adapted toproject intermediate the horns 24 and adjiacent the'perforations 14. rEhe position of the tube 20 isl inclined-as respects that of* thel tube 5 such that the inclfine'dI face isparall'el o r substantially par-j allel to the base offthe tube 5f when the parts are properlyY assembled with said tube 20 slidfalily engaging the inclined face 18 of thebl'ock 17'. The rear end of the tube 2O isadapted-'tobe connected to any source-of expansive Huid supply such asia-ir or's'team. V

lsuitalole screws -and acting as a support onwhich the tube 2O isslidable- Said block 29 has a screw-threaded bolt passi-ng there through carrying a nut- 31 fastenedV thereon and also provided with the usual head 32.

When the fuelI such- `as oilis forced throu-ghfthe-tfube- 5 it flows intothe' chamber formed! the slots 12 and 131 and through the perforatons 14 whereupon itis atomizedl by the expansive` fluid such as airV whiclr isforced through the tube 20. It vis then ignited by any suitablefl'ame (not shown) asfordinarilyv infburners o-f .this type.

' lhe spread-or iare of theratomized'fuel may be. varied in an obvious'manner` without changing the air pressure Vor volume;l ofair passingthrough the tube 20'A by" merelyV shorten-ing'- or lengthening the effective l length ofthe lipl` 24? Vby manipulation. ofthe nut 32;k rlhe-horns24.arelprovided to. guide the airflowing through the tube-20by con! finingf it between two side walls.

In Asome cases it will be found desirable in order to secure the best results to adjust the horizontal position of the tube 5 by movingV it forwardly or rearwardly on the block 17. Furthermore, if a flame of greater thickness'is desi-red this may' be secured by v raising the tubei vertically by mean-s of the adjusting screw 17 whereby a larger space willobtain between thejunder side of the.

tube kanl the outl'etopgening inthe. forward' 'endf21' offtl'ietube 20. The cap or head `10 Vispmade removable for purposes of cleaning and the tubesf plates and bars are all of standard shap'ewwhiclr. are machined tothe proper size and dimensions, thus making for cheap-ness and ease: ofv manufacture Further-merci thefparts are detachably'lfield toiy getherthus facilitating the repairof'fthef burner or replacement of anyofAV its parts'- should .theybecoine defective or broken.
